Mathematics

representation on number line

In Class 11 Mathematics, this topic develops a visual understanding of Linear Inequalities through the representation of numbers and solution sets on a number line. Students learn to locate real numbers, mark intervals, distinguish included and excluded endpoints, and interpret symbols such as <, >, ≤, and ≥. The topic also helps them read and communicate inequality solutions clearly, including cases where intervals are combined or restricted.

  1. A square bracket can be used to show that \(+\infty\) is included
  2. \(-\infty\) can be treated as an included endpoint of an interval
  3. Infinity is never a member of a solution set; therefore, an interval extending to infinity always uses a parenthesis at infinity
  4. Parentheses and square brackets have no different meanings in interval notation
